Pantented tamperproof device
Special security device that allows to lock the valve in open or closed position. It consists of a special nut and of the Sigilblock cap. Chrome finish. It is possible to put it both on the lever handles and on the “T” handles.

  • 1st size: for valves from 1/4” to 3/4” (from DN10 to DN20)
  • 2nd size: for valves 1” and 1”1/4 (DN25 and DN32)
  • 3rd size: for valves 1”1/2 and 2” (DN40 and DN50)
Exception: as concerns the filter ball valves (Art. 514, 514P, 564P) the size to be used is the 2nd. For the art. 514 1”1/4 the size to be used is the 3rd.

A special unlocking key is required to remove the lock (separately supplied).
SigilBlock is a special security device patented by BRV. It can be put on the valves provided with the lever handles and with the “T” handles and it allows to lock the valve in the fully closed or open position, according to the requested operating conditions.

SigilBlock, if compared to other locking systems, is a very flexible and good value device: it can be mounted on any standard BRV ball valve, both on the old models and on the new. Thanks to the compact size, it is room saving.
To mount it, it’s necessary to replace the nut of the standard handle with the special nut of the locking device and then to put the cap; once it is fitted, it can be removed only by authorized personnel, thanks to the special key.
How to apply Sigilblock device for locking a valve



Remove the handle’s nut. Screw the special nut and turn the handle to fully open or closed position. Insert the Sigilblock
cap up to the click.

How to remove Sigilblock cap to operate on the valve:


Insert the special Sigilblock key and, keeping
it pressed, pull the cap to the click.
Take off the key and pull out the cap.
Now you can operate on the ball valve.
